Hello everyone, after my battery discharged at 0% and the phone was off, I was no longer able to charge it with the connector.
Now it charged for all the night but the % is the same of yesterday. If I put it in charge in the external dock it works well.
I doubt it's the connector of the pèhone because until the battery was discharged it worked normally.
Till yesterday i used the Foxhound rom with Perseus kernel, now I use Revolution HD with stock kernel but nothing changed.
Any suggestions? Thanks
Are you using the OEM charger? They are known to be faulty/POS!

yes it is
but till 3 days ago everything was ok
i have 3 different chargers and they all don't work well after the battery went down
Battery voltage has dropped too low for standard charger to initiate charging, either obtain a special charger or replace your battery (cheaper).

Better to directrly put 5V on battery, but skills required

but if i use the external charger by samsung with the standard charger connected on it i can recharge my two batteries normally. don't they use the same voltage?

Charge the batterys to 100% then test the other chargers .
Could be dirty USB port poor cable .
Poor connectors .

i'm reading different opinions about this when i searched through the xda forums and on google.
i'm using the same custom rom and kernel for about a week now. a few days ago, i charged purely on wall socket. left overnight, my battery lost only 2%.
last night, i charged my phone when it was about 30%. i charged using usb up to 85%, then i finished it off on AC up to a 100%. my overnight loss went up to 5% (i did not install any additional apk, or change my setcpu profiles, etc).
there are no topics on this, specifically for SGS2. mostly are from HTC threads.
from what i learned, usb's only pour out about half of what AC's can give (500 mah vs 1,000 mah). does that translate into a poorer batt life?
How you charge your phone, usb vs AC will not effect the battery life, 100% is 100%, it will just charge slower via usb.

I have noticed something similar with my captivate.I would guess that when you use the wall charger with 1amp the battery gets more of a charge than when you use a usb charger at .5amps. 1amp can cause more chemical change in the battery than half an amp.
sent from my Infuse at Tranquility Base.
SGS2 will only let 650mA into the battery, AFAIK it's hardware restricted to do this. Wall charger will charge faster, but only slightly.
I see no difference and 2% to 5% is within a tolerable variation of overnight drain .
Its all the same electricity .

Firmware, actually, and the phone determines how much it will draw based on the resistance between the two USB data pins. If the resistance is < 200 ohms, it assumes it's plugged into an AC charger, and will draw up to 650 mA. Otherwise, it assumes it's plugged into a PC's USB 2.0 port, and will draw up to 450 mA, just under the 500 mA that a USB 2.0 port is supposed to provide, per the USB 2.0 spec.
Since it's firmware, it should be possible to change the current draw by re-compiling the kernel sources with new values. Note that you don't want to go too high on the charging current, as that could cause overheating or fire.

And how about charging a spare battery using a separate battery charger?
I have two batteries and I never charge them plugging the phone, just using a spare battery charger. Does it have any negative effect on the batteries' lifespan?
dont know what happened but my phone is being charged with ac adapter as same speed as usb.(more than 4 hours) :S
I have a USB charger capable of delivering 1A.
Even with the data pins shorted (phone side), it still seems to draw only 350 mA :-(
Any ideas?
Known made-up cables that do work?
I have a S2 and recently it started developing a problem where it charges slowly like it's plugged into the USB Port, tho it charges from a wall socket. If I let it charge for a bit like that and I unplug the wall charger from the socket and stick it back in it's all ok and charges normally.
Does this have smth to do with my charger or with my phone???
Recently I changed the rom and kernel so it's nothing related to that. (i'm on stock kernel, rooted now and before i was on what i have in my signature)
Thanks
I'd try using a different adaptor. If you're rooted I'd also recalibrate the battery. If problem persists a new battery may be needed.

I changed the battery not even a year ago... swtiched to the 2000mah one
I'm thinking a faulty charger that doesn't wanna charge unless he gets a bit heated up, as in a faulty capacitor
Dunno yet... will try the battery recalibrate stuff first

Go to Settings -> About phone -> Status. The Battery Status will show you how the phone is charging, by USB or AC. If you use the wall charger and the phone says Charging (USB) instead of Charging (AC) then your charger might be faulty.

Thank you, will try that and let you guys know what I find out.

Didn't try a new charger... tho i have an iphone one i could use with the usb cable... and see how it goes. But it seems the charger is faulty.
The problem is the charger. A wire was loose in the micro usb charger that tells the phone it's charging from the wall socket and not from usb

It's just settling in.
I have an old 0.7A charger and was told that a 1A charger would be faster..
But how far higher can I go? Is there a 2A charger?

1A is stock for S3.
Maximum recommended is 1.5A,more may brick your whole device,if not the battery.

I guess using modified"boeffla or googymax " kernels will let your phone charge much faster
Maximum rating of the charger is irrelevant, the phone will only draw a safe amount. If you override that limit then you may blow the internal charging IC or rupture the battery.
Don't post questions in the general section.
The S3 can't charger faster than 1A, it will only draw what it can, I've used a HP Touchpad 2A charger since the day I got the phone, it still won't draw more than 1A. You can use custom kernals to draw more, but you'll find lots of stories of people who did it and fried the charging board.
I tested using 1.1Ah, and for the storioes I've read, it's the maximum value you can use with security.
Hi, you can have more than 1A, but you need to change the limit with boeffla (i made it for the USB charge)

Using 1.2A from months in boeffla kernel without any trouble, using stock charger.
I tried 2A once and it was fast (0-100 in 1hr) but its not recommended 1.5 max
Also I increased charging speed to 1600mah that time and it was working

Dramatically increasing charging current will also dramatically decrease battery service life
Just get a second battery and desktop cradle, instant recharging without any wear on the phone motherboard.

Hi, i am getting a new charger for my tablet pc which uses a 5.35V 2A output charger and was wondering whether i can use this to charge my galaxy S3. so that i do not have to carry 2 chargers?
IS it advisable?
My S3 came with a 1A charger, my wife's S3 came with a 2A charger. I used her charger a few times and it worked fine. As of last week my charger is working fine, if I use hers with my phone I only shows "USB" in the battery info and takes forever to charge. I don't know if her charger did damage to my phone/battery but that felt strange, so I stopped using her charger.
hi,
i am facing problem with my device. it is charging at very slow speed like 0 % to 80% in 6 hours. i was using android revolution rom. it was working good and one night my phone started giving this problem.. now i am on stock rom.
i have tried changing chargers, i have used 3 samsung chargers and 1 motorola charger but it aint charging like before.
i have cleaned my charging port.
i blew in it many times.
i used boeffla kernel
but still it is not charging my phone at normal speed, it is very very slow.
I used a application "galaxy charging current"
With my 1st samsung charger i get readings
Reference:1098 ma
Maximum: 700 ma
Minimum:700 ma
With 2nd samsung chager
Reference :1098 ma
Maximum: 200 ma
Minimum:100ma
With motorola charger
Reference:1098 ma
Maximum:600ma
Minimum:600ma
I kept my phone off for some time, now it ia charging at better speed with 1st samsung charger
please help me

no, they are one-piece wall chargers.
and with time milliamperes decrease to 300 ma with all the chargers

If there are 3 cables, there only rests the socket of your phone or (unlikely) its charging-control. Otherwise: try another cable.
They are without cable.. Samsung travel adapter without usb..
You think the problem is with charger ?
Sorry, I didn't understand. No, it's very unlikely that 3 loaders fail. I supppose it's the socket of your phone or the internal hardware. So let it repair.

Try another battery.
my batteries just died, so i try to stream videos with my razr.
i have 4.0.4, the device have been rooted and rommed many times, i cant count.
i flashed an psasia 4.0.4.
the HDMI does not work neither.
and the device works properly without any battery attached, but only when i connect the cable to computer.
it doesnt work with wall charger (any of them, 1.2A, 1A, 0.5A).
any ideas how can i solve those problems?
use original charger and wait about 2 hour and then try power on.
if does not work open your razr and shock battery with high voltage

i have no original charger, they're all broken...
ive got 2.1A, 1.2A(nexus5) and two 1A...
all of them are 0.5V
the computer USB is 3.8V...
may i need a lower voltage?

open your phone and disconnect cable from battery to phone and shock your battery
